Bart, all,
This is originally what I was hoping to learn from this thread.   I argued
that aluminum works well as a TC primary, but was hoping that someone could
explain why an aluminum gap would work better than copper or other material.
I have two, one inch aluminum spheres that were used for corona suppression on
a high voltage transformer's output connections, but never tried them as a TC
gap.  It seemed like the pitting would be severe and they wouldn't last long,
but now may have to try them out.
